Description

Technical Field

[0001] This invention relates to the field of decomposer burner technology, specifically to a decomposer burner structure for optimizing the combustion efficiency of a rotary kiln. Background Technology

[0002] A low-NOx burner disclosed in authorization announcement number CN113339794A includes: a shell having a receiving cavity; a bellows plate disposed within the receiving cavity to divide the receiving cavity into a bellows chamber and a mounting cavity, the mounting cavity including a first opening disposed opposite to the bellows plate in a first direction; a plurality of combustion tubes mounted on the bellows plate and extending along the first direction; and a flame nozzle tube including a first air pipe and a first gas pipe extending along the first direction, the first air pipe mounted on the bellows plate and sleeved on the first gas pipe, the first air pipe and the first gas pipe defining a first air passage, the first gas pipe including a straight section and a gradually expanding section. This device has the advantages of high combustion stability and complete combustion.

[0003] The following problems were found after using the existing low-NOx burners:

[0004] 1. For burners, the degree of mixing between air and fuel is crucial. The above solution lacks a corresponding mixing mechanism to ensure sufficient mixing of air and fuel. During use, incomplete combustion of fuel will produce a large amount of air pollutants, which will harm the health of workers and damage the environment.

[0005] 2. In the above scheme, the shell lacks a filter structure for the gas. Impurities mixed in the gas are also one of the reasons for incomplete combustion of the gas. Furthermore, impurities can clog the igniter, resulting in uneven heating of the decomposition furnace by the igniter, which in turn leads to a reduction in the quality of the cement. Summary of the Invention

[0006] The purpose of this invention is to provide a decomposition furnace burner structure for optimizing the combustion efficiency of rotary kilns, so as to solve the problems of uneven mixing of air and fuel gas and impurities in the gas affecting the combustion of fuel gas.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A decomposition furnace burner structure for optimizing the combustion efficiency of a rotary kiln includes a shell, an air supply mechanism inside the shell, a chamber on one side of the shell, an ignition mechanism at one end of the chamber, a pipe at the bottom of the shell, an air pipe and a gas pipe on the surface of the pipe, a first mixing mechanism for initially mixing air and gas inside the pipe, a second mixing mechanism for secondary mixing air and gas inside the chamber, and a cleaning mechanism for filtering impurities in the gas inside the chamber, the cleaning mechanism connecting the first mixing mechanism and the second mixing mechanism.

[0009] The first mixing mechanism includes a first motor, a drive shaft, and stirring rods. The drive shaft is rotatably disposed at the center of the bottom of the pipe. The first motor is fixed to the bottom of the pipe, and the output end of the first motor passes through the pipe and is keyed to the drive shaft. The stirring rods are evenly distributed on the surface of the drive shaft.

[0010] The first motor drives the stirring rod to rotate via the drive shaft. The stirring rod initially mixes the air and gas in the pipeline, and then sends the gas mixture into the chamber for secondary mixing via the gas delivery mechanism. The gas mixture first passes through the cleaning mechanism in the chamber and then enters the second mixing mechanism for secondary mixing, and finally passes through the ignition mechanism for combustion.

[0011] As a preferred embodiment of the present invention, the second mixing mechanism includes a piston cylinder, a piston plate, a guide rod, a one-way inlet pipe, and a one-way outlet pipe. The piston cylinder is disposed inside the chamber. One end of the guide rod passes through the surface of the piston cylinder and is slidably disposed inside the piston cylinder. One end of the piston plate is fixed to the center of one end of the guide rod and is movably disposed inside the piston cylinder. The one-way outlet pipe is fixed at the outlet of the piston cylinder, and the one-way inlet pipe is fixed to the surface of the piston cylinder.

[0012] As a preferred embodiment of the present invention, the cleaning mechanism includes a driving component, a traction shaft, a bracket, a first bevel gear, a second bevel gear, a limiting component, and a perforated plate. The first bevel gear is fixed to one end of the traction shaft, and the second bevel gear is fixed to one end of the driving shaft. The first bevel gear and the second bevel gear mesh with each other. The bracket is fixed to the inner wall of the chamber. The traction shaft passes through and is rotatably disposed on the surface of the bracket. The bracket and the traction shaft are connected by a bearing. The driving component is disposed at one end of the traction shaft and is used to drive the guide rod to move. The limiting component is disposed between the ignition mechanism and the bracket and is used to restrict the driving component from making linear movements within the chamber. The perforated plate is fixed to the driving component and is used to filter impurities in the gas mixture.

[0013] As a preferred embodiment of the present invention, the driving component includes a sleeve, a groove, and a spherical protrusion. One end of the sleeve is fixed to the guide rod, and the other end of the sleeve is movably disposed on the traction shaft. The groove is formed inside the sleeve and is configured as a spiral structure. The spherical protrusion is fixed to the surface of the traction shaft and engages with the groove.

[0014] As a preferred embodiment of the present invention, the limiting member includes a limiting arm and a limiting rod. The limiting arm is fixedly disposed on the surface of the sleeve, the limiting rod is fixed between the ignition mechanism and the bracket, the limiting arm is slidably disposed on the surface of the limiting rod, and the perforated plate is fixed on the surfaces of the limiting arm and the sleeve.

[0015] As a preferred embodiment of the present invention, the ignition mechanism includes a fixed base, a main flamethrower, auxiliary flamethrowers, and a connecting pipe. The fixed base is installed at one end of the chamber, and one end of the limiting rod is connected to the surface of the fixed base. The main flamethrower is provided at the center of the fixed base, and at least eight auxiliary flamethrowers are provided on the surface of the chamber. The main flamethrower and the auxiliary flamethrowers are connected by a connecting pipe.

[0016] As a preferred embodiment of the present invention, the air supply mechanism includes a second motor, a main shaft and fan blades. The main shaft is rotatably disposed on the inner wall of the housing, the fan blades are fixed to the surface of the main shaft, and the second motor is mounted on the surface of the housing. The output end of the second motor passes through the housing and is keyed to the main shaft.

[0017] As a preferred embodiment of the present invention, a support frame is fixed to the inner wall of the housing, the drive shaft passes through the center of the support frame, and the drive shaft and the support frame are connected by a bearing.

[0018] The present invention, through the setting of the first mixing mechanism, enables the air and gas inside the air pipe and the gas pipe to be initially mixed under the action of the stirring rod after entering the pipe, so that the air and gas are mixed together more evenly. Furthermore, through the setting of the air supply mechanism, the gas mixture of air and gas can be sent into the chamber for secondary mixing, thereby ensuring that there is sufficient air involved in the combustion of gas and preventing the phenomenon of incomplete combustion of gas.

[0019] The present invention, through the setting of the second mixing mechanism, can remix the gas mixture inside the chamber. In the second mixing mechanism, the one-way air inlet pipe draws the gas mixture into the piston cylinder in a metered manner. During this process, the gas mixture will undergo a certain degree of mixing. After the piston plate reverses its movement, it can transport the gas mixture to the ignition mechanism through the one-way air outlet pipe. During this process, the gas mixture will be mixed again, thereby realizing the remixing of air and gas and further preventing the phenomenon of incomplete combustion of gas.

[0020] This invention, through the setting of a cleaning mechanism, can filter impurities in gas or air inside the chamber, thereby achieving the function of cleaning the gas. In the cleaning mechanism, since the sleeve moves back and forth on the surface of the traction shaft, the orifice plate as a whole also moves back and forth inside the chamber. This movement of the orifice plate prevents impurities from accumulating inside the holes on the surface of the orifice plate, thus preventing the orifice plate from affecting the filtration effect of the air or gas. Overall, it can further prevent the phenomenon of incomplete combustion of gas.

[0021] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention can be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-8 The present invention provides an embodiment of a decomposition furnace burner structure for optimizing the combustion efficiency of a rotary kiln, comprising a shell 1;

[0033] like Figure 1 , 2 As shown in Figures 3 and 4, a gas supply mechanism 2 is provided inside the housing 1, a chamber 3 is provided on one side of the housing 1, an ignition mechanism 4 is provided at one end of the chamber 3, a pipe 5 is provided at the bottom of the housing 1, an air pipe 6 and a gas pipe 7 are provided on the surface of the pipe 5, and a first mixing mechanism 8 for initially mixing air and gas is provided inside the pipe 5. A second mixing mechanism 9 for secondary mixing of air and gas is provided inside the chamber 3. A cleaning mechanism 10 for filtering impurities in the gas is also provided inside the chamber 3. The cleaning mechanism 10 connects the first mixing mechanism 8 and the second mixing mechanism 9.

[0034] The first mixing mechanism 8 includes a first motor 81, a drive shaft 82, and stirring rods 83. The drive shaft 82 is rotatably disposed at the center of the bottom of the pipe 5. The first motor 81 is fixed to the bottom of the pipe 5, and the output end of the first motor 81 passes through the pipe 5 and is keyed to the drive shaft 82. The stirring rods 83 are evenly distributed on the surface of the drive shaft 82.

[0035] The first motor 81 drives the stirring rod 83 to rotate via the drive shaft 82. The stirring rod 83 initially mixes the air and gas in the pipe 5, and then sends the gas mixture into the chamber 3 for secondary mixing via the gas supply mechanism 2. The gas mixture in the chamber 3 is first filtered by the cleaning mechanism 10 and then enters the second mixing mechanism 9 for secondary mixing, and finally combusted by the ignition mechanism 4.

[0036] The first mixing mechanism 8 allows the air and gas inside the air pipe 6 and gas pipe 7 to be initially mixed under the action of the stirring rod 83 after entering the pipe 5. The second mixing mechanism 9 can further mix the gas mixture inside the chamber 3 and, together with the cleaning mechanism 10, filter impurities in the gas or air to achieve the effect of cleaning the gas.

[0037] like Figure 4 As shown, the second mixing mechanism 9 includes a piston cylinder 91, a piston plate 92, a guide rod 93, a one-way air inlet pipe 94, and a one-way air outlet pipe 95. The piston cylinder 91 is disposed inside the chamber 3. One end of the guide rod 93 passes through the surface of the piston cylinder 91 and is slidably disposed inside the piston cylinder 91. One end of the piston plate 92 is fixed to the center of one end of the guide rod 93, and the piston plate 92 is movably disposed inside the piston cylinder 91. The one-way air outlet pipe 95 is fixed at the outlet of the piston cylinder 91, and the one-way air inlet pipe 94 is fixed to the surface of the piston cylinder 91.

[0038] When the traction shaft 102 moves, it can pull the guide rod 93 to move synchronously. At this time, the guide rod 93 can drive the piston plate 92 to move closer to the traction shaft 102 inside the piston cylinder 91. At this time, the pressure inside the piston cylinder 91 decreases, and the gas mixture inside the chamber 3 can enter the piston cylinder 91 through the one-way air inlet pipe 94. When the second motor 21 switches the direction, the sleeve 1011 can push the guide rod 93 to move synchronously, thereby increasing the pressure inside the piston cylinder 91, so that the gas mixture inside the piston cylinder 91 enters the main flamethrower 42 through the one-way air outlet pipe 95.

[0039] like Figure 7 and 8As shown, the cleaning mechanism 10 includes a drive component 101, a traction shaft 102, a bracket 107, a first bevel gear 103, a second bevel gear 104, a limiting component 105, and a perforated plate 106. The first bevel gear 103 is fixed to one end of the traction shaft 102, and the second bevel gear 104 is fixed to one end of the drive shaft 82. The first bevel gear 103 and the second bevel gear 104 mesh with each other. The bracket 107 is fixed to the inner wall of the chamber 3. The traction shaft 102 passes through and is rotatably mounted on the surface of the bracket 107. The bracket 107 and the traction shaft 102 are connected by a bearing. The drive component 101 is located at one end of the traction shaft 102 and is used to drive the guide rod 93 to move. The limiting component 105 is located between the ignition mechanism 4 and the bracket 107 and is used to limit the linear movement of the drive component 101 in the chamber 3. The perforated plate 106 is fixed on the drive component 101 and is used to filter impurities in the gas mixture.

[0040] When the drive shaft 82 rotates, it can drive the traction shaft 102 to rotate synchronously through the cooperation of the first bevel gear 103 and the second bevel gear 104. Through the setting of the drive component 101 and the periodic forward and reverse rotation of the second motor, the perforated plate 106 can be driven to reciprocate linearly inside the chamber 3. By moving the perforated plate 106, impurities are prevented from accumulating inside the holes on the surface of the perforated plate 106, thereby preventing impurities from affecting the filtration effect of the perforated plate 106 on air or gas.

[0041] like Figure 7 As shown, the drive component 101 includes a sleeve 1011, a groove 1012, and a spherical protrusion 1013. One end of the sleeve 1011 is fixed to the guide rod 93, and the other end of the sleeve 1011 is movably disposed on the traction shaft 102. The groove 1012 is formed inside the sleeve 1011 and is configured as a spiral structure. The spherical protrusion 1013 is fixed to the surface of the traction shaft 102 and is engaged in the groove 1012.

[0042] The spherical protrusion 1013 drives the sleeve 1011 to rotate synchronously through the sliding groove 1012. However, since the limiting arm 1051 is fixed on the surface of the sleeve 1011, and the limiting arm 1051 can only slide on the limiting rod 1052, it cannot make the sleeve 1011 rotate in the circumferential direction. Therefore, the sliding groove 1012 on the surface of the spherical protrusion 1013 cannot rotate. So, as the spherical protrusion 1013 rotates continuously, it will make the sleeve 1011 move linearly on the surface of the traction shaft 102 through the sliding groove 1012.

[0043] like Figure 7As shown, the limiting member 105 includes a limiting arm 1051 and a limiting rod 1052. The limiting arm 1051 is fixedly disposed on the surface of the sleeve 1011, and the limiting rod 1052 is fixed between the ignition mechanism 4 and the bracket 107. The limiting arm 1051 is slidably disposed on the surface of the limiting rod 1052, and the perforated plate 106 is fixed on the surfaces of the limiting arm 1051 and the sleeve 1011.

[0044] Normally, the spherical protrusion 1013 would drive the sleeve 1011 to rotate synchronously through the groove 1012. However, now the sleeve 1011 is circumferentially fixed due to the cooperation between the limiting arm 1051 and the limiting rod 1052. Therefore, the sleeve 1011 can only move linearly in the axial direction, thereby achieving the reciprocating movement of the sleeve 1011.

[0045] like Figure 5 and 6 As shown, the ignition mechanism 4 includes a fixed base 41, a main flamethrower 42, an auxiliary flamethrower 43, and a connecting pipe 44. The fixed base 41 is installed at one end of the chamber 3, and one end of the limiting rod 1052 is connected to the surface of the fixed base 41. The main flamethrower 42 is provided at the center of the fixed base 41, and at least eight auxiliary flamethrowers 43 are provided on the surface of the chamber 3. The main flamethrower 42 and the auxiliary flamethrowers 43 are connected by the connecting pipe 44.

[0046] If only the main burner 42 is used for ignition, then only the area near the main burner 42 can achieve efficient combustion in the decomposition furnace. However, by setting at least eight auxiliary burners 43, which are equidistantly arranged around the main burner 42, the overall combustion range of the gas mixture is increased, thereby enabling more pulverized coal to burn in the decomposition furnace.

[0047] like Figure 1 , 2 As shown in Figure 3, the air supply mechanism 2 includes a second motor 21, a main shaft 22 and a fan blade 23. The main shaft 22 is rotatably mounted on the inner wall of the housing 1, and the fan blade 23 is fixed to the surface of the main shaft 22. The second motor 21 is mounted on the surface of the housing 1, and the output end of the second motor 21 passes through the housing 1 and is keyed to the main shaft 22.

[0048] The second motor 21 can drive the fan blade 23 through the main shaft 22. When the fan blade 23 rotates, it can transport the gas mixture inside the pipe 5 into the chamber 3, thereby achieving a stable supply of the gas mixture.

[0049] like Figure 3 As shown, a support frame 11 is fixed to the inner wall of the housing 1, and a drive shaft 82 passes through the center of the support frame 11. The drive shaft 82 and the support frame 11 are connected by a bearing.

[0050] Since the drive shaft 82 is only connected to the bottom of the pipe 5 at one end, during the long-term transportation of air and gas, the drive shaft 82 is prone to shaking or tilting inside the pipe 5 due to its own weight, which will cause the first bevel gear 103 and the second bevel gear 104 to fail to mesh accurately. The support frame 11 can support and fix the drive shaft 82 from the other end, thereby ensuring the accurate meshing between the first bevel gear 103 and the second bevel gear 104.

[0051] Working principle: First, the first motor 81 drives the drive shaft 82 to rotate. When the drive shaft 82 rotates, it drives the stirring rod 83 to rotate synchronously. Air and gas enter the pipe 5 through the air pipe 6 and the gas pipe 7 respectively, so that the stirring rod 83 can initially stir and mix the air and gas inside the pipe 5. Then, the second motor 21 drives the fan blade 23 to rotate through the main shaft 22, so that the fan blade 23 transports the gas mixture to the chamber 3 inside the housing 1.

[0052] After entering the chamber 3, the gas mixture can only pass through the holes on the surface of the perforated plate 106, thus filtering impurities in the gas mixture. When the drive shaft 82 rotates, it drives the traction shaft 102 to rotate synchronously through the engagement of the first bevel gear 103 and the second bevel gear 104. The rotation of the traction shaft 102 drives the spherical protrusions 1013 on its surface to rotate synchronously. Under normal circumstances, the spherical protrusions 1013 drive the sleeve 1011 to rotate synchronously through the sliding groove 1012. However, because the limiting arm 1051 is fixed to the surface of the sleeve 1011, and the limiting arm 1051 can only slide on the limiting rod 1052 and cannot allow the sleeve 1011 to rotate circumferentially, the sliding groove 1012 on the surface of the spherical protrusions 1013 cannot rotate. Therefore, as the spherical protrusions 1013 rotate continuously, they cause the sleeve 1011 to rotate horizontally on the surface of the traction shaft 102 through the sliding groove 1012. When the traction shaft 102 moves, it can pull the guide rod 93 to move synchronously. At this time, the guide rod 93 can drive the piston plate 92 to move closer to the traction shaft 102 inside the piston cylinder 91. At this time, the pressure inside the piston cylinder 91 decreases, and the gas mixture inside the chamber 3 can enter the piston cylinder 91 through the one-way air inlet pipe 94. When the second motor 21 switches the direction, the spherical protrusion 1013 is exactly located at one end of the slide groove 1012. Then, the spherical protrusion 1013 can drive the sleeve 1011 to move in the opposite direction through the slide groove 1012. The sleeve 1011 can push the guide rod 93 to move synchronously, thereby increasing the pressure inside the piston cylinder 91. This causes the gas mixture inside the piston cylinder 91 to enter the main flamethrower 42 through the one-way air outlet pipe 95. Part of the gas mixture will be ignited and burned through the main flamethrower 42, while the other part will enter the auxiliary flamethrower 43 through the connecting pipe 44 and be ignited and burned.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
